US Patent:

53414292, Aug 23, 1994

Filed:

Dec 4, 1992

Appl. No.:

7/986105

Inventors:

John W. Stringer - Santa Cruz CA
Theodore S. Richards - Los Gatos CA

Assignee:

TestDrive Corporation - Santa Clara CA

International Classification:

H04K 100

US Classification:

380 23

Abstract:

A bidirectional process allows remote transformation of ephemeral materials between an original form and a denatured form without changing the content of the material from its original form and without restricting the resolution, functionality, and/or utility of the original material in the denatured form. The denatured material provides both a limited use form, which allows temporary full function evaluation of the material; and an enabled form, which allows unrestricted full function use of the material. A security system supervises conversion of the denatured material from the limited use form to the enabled form.

International Classification:

H04L 900

US Classification:

380 4

Abstract:

Virtualization converts a normally unidirectional process into a bi-directional process to permit automatic install and uninstall of new material, addition and/or modification of target materials while preserving the state of target material, and conversion of materials having a specific media characteristic into an extended range of media characteristics. Applications include temporary retooling of assembly line for short production runs, associating the installation of materials with the mounting of removable media and the uninstalling materials with the unmounting of removable media, and repurposing stand-alone applications for client-server environments without requiring modifications to the design of the stand-alone application.
